The stool of a healthy life has three legs: nutrition, exercise and sleep. We shun unnatural substances from our food — locally-grown and organic offerings are exploding, even at Walmart. We insist on better fare in school cafeterias than what was dished up when I was a kid. Back then, everything was served with a single ice cream scoop, and your ball of turkey tetrazzini risked rolling over your ball of “green” beans. As for performance-enhancing substances, just ask Lance about our tolerance for those. Why is sleep the odd leg out? In the U.S. over 9 million people use prescription sleep medications. With one termite-ridden leg, the holistic wellness stool topples over. It is within our power to do better, particularly in the era of wearable technology.
